Look closely at the panel running down the middle of this photo. The left side has been cleaned. The right side hasn't yet.
Same panel, same sunlight, completely different output.
That's the part most solar owners never get to see. Dirty panels don't shut down or send you a warning. Your generation just drops a little each month, and it usually gets written off as cloudy weather or a slow season.
Cleaning them properly matters more than most people expect. We use deionised water at controlled pressure, so there's no scratching and no white hard-water marks left behind on the glass. We work early morning or late evening, because spraying cold water on hot panels can crack them. And we check your actual generation before and after, so you can see what came back.
A garden hose, borewell water and a housekeeping brush can cost you more in damage than the cleaning saves.
Dr.eTech has spent 7+ years on solar operations and maintenance out of Ahmedabad, working across India. We handle panel cleaning, preventive and breakdown maintenance, thermal imaging, performance monitoring and full asset management for rooftop, commercial and industrial plants.
When was your plant last cleaned or inspected? If you're not sure, that's usually a sign. Give us a call and we'll take a look.
